Our 2019 Tribute in Light Bird Monitoring
Our agreement with partners National September 11 Memorial & Museum and Michael Ahern Production Services calls for the lights to be turned off when necessary to allow migratory birds that are disoriented in the beams to disperse. (Learn how artificial light from the Tribute in Light affects nocturnally migrating birds in this Audubon Magazine article here). As always, we were joined by Dr. Andrew Farnsworth’s BirdCast team, who kept us informed of bird migrations throughout New York City and the surrounding area.
Our protocol is to ask that the lights be turned off if a critical mass of birds (over 1,000) is counted circling in the beams at one time, or if birds are observed circling and calling low in the beams. The Tribute in Light organizers and production team are always respectful of our requests, and we cannot thank them enough for continuing to work with us to ensure the Tribute in Light is safe for our nocturnally migrating birds.
This year’s Tribute in Light monitoring began with very light bird migration. Our volunteers saw very few birds circling in the lights, with the notable exception of an opportunistic Peregrine Falcon hunting for potential easy meals, first spotted around 8:30 p.m. We remained optimistic for a light migration as the night continued. We observed a few birds, such as a Yellow-billed Cuckoo, moving quickly through the lights and continuing on its flight. We also watched Eastern Red Bats and Silver-haired Bats forage in the lights.
So far been a quiet night for birds at the #tributeinlight. Great news! Things can always change, though, over the course of the long night, so our dedicated volunteers will continue to closely monitor the tribute until dawn to make sure our nocturnally migrating birds are safe! pic.twitter.com/r27vMzjh43— NYC Audubon (@NYCAudubon) September 12, 2019
The #TributeinLight organizers have agreed to turn off the lights for 15 minutes to allow a high quantity of birds caught in the lights to disperse and continue safely on their migration. Thank you to the Tribute for working with us once again to make tonight safer for birds! pic.twitter.com/uk90OyyVL9— NYC Audubon (@NYCAudubon) September 12, 2019
